Title: Image processing system
Inventor: TSUJI KAZUTAKA
IPC: G03F1/00
Filed: 1990-03-08
Abstract: PURPOSE:To eliminate the deterioration in quality by the jaggy generated in the edge parts of rebinarized images by setting the density value of the locus where an ideal edge line and the locus of the density value by an interpolation method are most proximate as the value of threshold. CONSTITUTION:A color photographic image is inputted to a color scanner 1. Image data and the cut out mask data thereof are registered on an optical disk 3 via a magnetic disk 2. A computer 4 subjects the data to geometric conversion processing and subjects the respective picture elements of the cut out mask data after processing to rebinarization processing by the prescribed threshold. The ideal edge line and the locus of the respective density values by the interpolation method are defined with respective to the edge part in the interpolation method of this time and the density value of the locus where the defined ideal line and the locus are most proximate is calculated. This value is determined as the adequate threshold.

Title: Device for inspecting printer matter
Inventor: MIKAMI NORIAKI
IPC: G06T7/00
Filed: 1990-03-08
Abstract: PURPOSE:To permit detection of a defective printing small in size or concentration difference by comparing the cumulative value obtained from an accumulating means with the reference cumulative value of a second memory means to judge as to whether or not printed matter is acceptable. CONSTITUTION:At the start of inspection, a subcontroller 20 sends an arithmetic and control signal CA to an arithmetic circuit 17 to cause operation to be effected. After starting of the inspection, the subcontroller 20 supplies a submemory signal CM to a tolerance value submemory 18, each time it detects a designated line from a point where the operation is effected on a predeter mined number of lines. The tolerance value submemory 18 stores the reference information equivalent to the results of the accumulation effected in the arithme tic circuit 17 and such reference information is sent to a comparative circuit 15 as a tolerance subdata SAD by the submemory signal CM. A subcomparative circuit 19 compares cumulative data SD with the tolerance subdata SAD and, if the size of the former is larger than that of the latter, a defective printing is judged as occurring and an error signal Es is sent to CPU 21.

Title: Ghost eliminating device
Inventor: TANAKA TADAAKI
IPC: H04N5/21
Filed: 1988-03-11
Abstract: PURPOSE:To control the tap gain in a feedforward form for improvement of the response speed and the ghost elimination accuracy by using a processing part to divide the output of a waveform converting part with a reference waveform Fourier coefficient and to supply the adversely Fourier transformed coefficient to a transversal filter as the tap gain. CONSTITUTION:The result of division of a division circuit 16 undergoes the adverse Fourier transformation via an adverse Fourier transformation circuit 18 and is used as the tap gain of a transversal filter 1. Thus a pseudo ghost is obtained. A correction circuit 17 emphasizes the high band component of the divided value received from the circuit 16 and regards a sudden drop of a specific frequency of the divided value as a beat disturbance to perform various types of correction processes to rise said specific frequency up to a level of the peripheral divided value, etc. The pseudo ghost produced by the filter 1 has a phase adverse to the ghost included in the received TV signal end is added to said ghost via an addition circuit 3 in terms of offset. Then the TV signals free from any ghost are supplied to a signal processing part through an output terminal OUT. In such a way, the response speed and the ghost elimination accuracy can be improved.

Title: Semiconductor laser device
Inventor: TAKANO SHINJI
IPC: H01S5/00
Filed: 1986-03-18
Abstract: PURPOSE:To obtain a semiconductor laser capable of controlling relaxation oscillation in pulse modulation and performing a ultra high speed pulse modulation by making part of an active layer a current uninjectable region. CONSTITUTION:A current uninjectable region is formed in a position in an active layer wherein the field strength distribution of light is maximum in the direction of an resonator axis. Although current is injected into a laser and a laser oscillation is initiated, an uninjectable region (a saturable absorber) absorbs light and a condition is moved in a direction shown by an arrow in Fig. 3. When the uninjectable region is present in part, light is absorbed until a saturation point S is reached as shown in Fig. (b) and thereafter a medium becomes transparent. Accordingly, a rectangular waveform wherein a relaxation oscillation is restrained is obtained as a light output waveform. For such effect, the optimization of parameters, such as the volume of the uninjectable region, a carrier density and the like, and, when the field strength distribution of light is largely different depending on the direction of the resonator axis as in the case of DFB or the like, also the optimization of the position and the like of the injectable region are actually effective.

IPC: G03G15/01
Filed: 1990-03-12
Abstract: PURPOSE: To improve the throughput of a machine by providing a means for forming a 1st path extended to the entrance from the exit of a working spot and a means capable of selectively operating to transfer a medium to a 2nd path longer than the 1st path and leading to the entrance from the exit of the working spot. CONSTITUTION: The 1st path has length enough only for the shortest medium sheet and the 2nd path which can be selectively operated to carry the medium to the entrance from the exit of the working spot is provided. By making the 2nd path longer than the 1st path in the moving direction of the medium, the long medium sheet can be handled without sacrificing the throughput speed of the machine in the case of handling the short medium. A drum can be included in the constitution of the 1st and the 2nd paths. In such a case, the drum 24 in the 1st path has the outer peripheral length corresponding to the shortest medium handled in the machine. Thus, the media of various sizes are processed without making the maximum throughput speed low.

Title: Refregerant compressor
Inventor: MORIKAWA YOSHIYUKI
IPC: F04C28/26
Filed: 1978-05-16
Abstract: PURPOSE: For preventing the flow of high-pressure lubricating oil in a cylinder, to raise the internal pressure of the low-pressure section by making continuity of the  high and low sides upon the stoppage of a compressor.  
     CONSTITUTION: When the operation of a compressor 1 is stopped, a discharge valve 24 closes, and the internal pressures of a discharge passage 23 and a high pressure passage 29 lower. At this time, the internal pressure of a discharge space 25 and said high-pressure passage 31 are still kept high so that a plunger 30 transfers rightward counter to the force of a spring 34. Consequently, passages 37 and 38 intercommunicate, the internal pressure of the chamber of said spring 34 lowers quickly, and a plunger 30 transfers rightward counter to the force of said spring 34. Therefore, passages 35 and 36 intercommunicate, and pressure transfers to raise the internal pressure of said low-pressure section and compressing chamber 22. Thereby, the pressure of the lubricating oil in a separator 4 is reduced. Since internal pressure of said compressing chamber 22 is raised thereby, the pressure differential of said lubiricating oil ceases to exist so that lubricating oil is prevented from flowing into said compressing chamber 22.
